Drainage pit and combination with a plate-shaped element

The invention relates to a drain for fixing to a plate, such as a foam plate, which drain comprises:

- a receptacle with a bottom, a wall standing up along the circumference of the bottom and a discharge opening;

- a fixing ring with a circumferential wall hanging down on the inner edge of the ring, which hanging circumferential wall extends within the upright wall of the receiving bin;

- a sealing ring arranged between the hanging circumferential wall and the upright wall; and

- coupling means for coupling the fixing ring to the receiving bin.

When installing a sanitary room, a plate-shaped element is used as a base for a tiled floor in specific applications. A such a plate-shaped element can easily be provided with a slope, so that no effort has to be made to obtain the correct slope when pouring a concrete floor or tiling a floor.

In addition, such plate-shaped elements are usually designed as a foam plate, whereby sound insulation is obtained.

When mounting, the foam plate, in which an opening is provided, must be positioned with the opening above a floor drain installed in the floor. A watertight connection must then be provided. To this end, it is known to screw a fastening ring into the collecting tray from above, whereby the plate-shaped element is clamped between the collecting tray and the fastening ring.

The disadvantage of such a connection is that it is unclear how tight the fixing ring must be screwed for a correct connection. Leakage can occur if the connection is not tightened sufficiently. In addition, the length of the thread is usually limited, making it difficult to absorb thickness differences. Furthermore, the collecting tray is attracted to the foam plate, as a result of which tension can arise in the discharge pipe or the foam plate can be deformed.

It is therefore an object of the invention to reduce or even prevent the abovementioned disadvantages.

This object is achieved according to the invention with a drain according to the preamble, which is characterized in that the coupling means comprise at least one resilient finger arranged parallel to the upright wall and on the inside of the upright wall, wherein the at least one resilient finger has a first edge disposed at the free end;

and wherein the coupling means comprise a second edge arranged on the hanging circumferential wall and directed in radial direction, which second edge engages the first edge of the finger upon axial displacement of the upright wall relative to hanging wall.

A snap connection is formed with the coupling means according to the invention. If a click is heard when mounting the mounting ring on the collecting tray, it will immediately be clear that both parts are correctly coupled. During assembly, therefore, a plate-shaped element with mounting ring can be placed on the bottom tray in one movement and coupled to it.

Furthermore, since a sealing ring is arranged between the hanging circumferential wall and the upright wall, a watertight connection will be formed at all times between the collecting tray and the fixing ring. This seal is independent of the click connection. A good seal is thus guaranteed independently of the snap connection. In addition, the fastening ring can continue to shift relative to the collection tray, as a result of which thickness differences can easily be absorbed, as well as small angular differences between the fastening ring and the collection tray. Therefore, no deformation of the foam plate or of the drain pipe will occur.

Furthermore, since the at least one resilient finger is arranged on the inside of the upright wall, it can moreover be easily checked whether the click connection has been properly established, for example by feeling or viewing the finger.

In a preferred embodiment of the drain according to the invention, the at least one resilient finger is arranged on an insert, which insert is removably arranged in the upright wall of the receiving tray.

By placing the resilient fingers on inserts, the fingers can easily be replaced if, for example, a finger is damaged during assembly. In addition, the fingers can optionally be adapted to the type of fastening ring that will be coupled to the collection tray. Furthermore, the collecting tray can thus also be used for other versions without fingers, which reduces the production costs.

In a further embodiment of the drain according to the invention, the insert part comprises a hook part, which hook part projects into a recess in the upright wall of the receiving tray.

In a very preferred embodiment of the invention, the raised wall comprises a circumferential groove for receiving the sealing ring and the recess is arranged in the groove and extends parallel to the circumferential wall.

By hooking the inserts into a recess in the circumferential groove and then placing a sealing ring in the circumferential groove, the inserts cannot accidentally come off. Only when the sealing ring is removed again can the inserts be removed.

In yet another embodiment of the drain according to the invention, the second edge is directed inwards in radial direction.

As a result, the resilient finger will engage the second edge in a radial direction from the inside to the outside and the fingers can easily be disconnected via the opening.

In yet another embodiment of the drain according to the invention, the coupling means comprise at least three resilient fingers. These three fingers are preferably evenly distributed along the circumference, so that a stable and sturdy coupling can be obtained.

The invention further comprises a combination of a drain according to the invention and a plate-shaped element, such as a foam-shaped slope plate, wherein an opening is provided in the plate-shaped element, the securing ring being arranged around the opening in the upper surface of the plate-shaped element, the hanging wall protrudes into the opening and wherein the collecting tray is arranged against the underside of the plate-shaped element, wherein the upright wall falls within the opening of the plate-shaped element and the fixing ring is coupled to the collecting tray.

Figure 1 shows a perspective view of a first embodiment with exploded parts.

Figure 2 shows a cross-sectional view of the embodiment according to Figure 1.

Figure 3 shows a second embodiment in cross-sectional view.

Figure 4 shows a cross-sectional view of a combination according to the invention.

Figure 1 shows a perspective view of a first embodiment 100 with exploded parts. In this embodiment 100, the drain is provided with a collection tray 101, which has a tubular drain opening 102 for further connection to a further drain pipe. The collecting tray 101 is provided on the top with a ring 103 which, when assembled, is welded to the upright wall 104 of the collecting tray 101.

Recesses 105 are provided in the upright wall 104 of the receiving tray 101, into which inserts 106 can be placed. Each resilient member 106 is provided with a resilient finger with an edge 107 which extends outward in a radial direction.

Figure 2 shows a cross-sectional view of the embodiment 100 according to Figure 1. The ring 103 is welded to the upright wall 104, so that a groove 108 is formed above the inserts 106, in which a sealing ring 109 is placed. This sealing ring 109 prevents the insert part 106 from being taken out of the collecting bin 101.

There is furthermore a mounting ring on the collecting bin 101

110 with an outlet 114 of a drain 115 arranged therein. The mounting ring 110 has a hanging wall 111 which seals on the sealing ring 109. On the hanging wall 111 there is further provided a wall with lip 112 which cooperates with the edge of the resilient finger 107 and prevents the hanging wall 111 from coming out of the receptacle 101 can be taken.

The wall with lip 112 forms an outlet in which a second seal 113 is provided and in which the outlet 114 of the drain 115 can then be placed. This allows the drain 115 to be adjusted in height to the thickness of the surrounding tiles or other floor.

Figure 3 shows a second embodiment 120 in cross-sectional view, which is largely the same as the embodiment 100 of Figure 5. The same parts are therefore designated with the same reference numerals.

The fixing ring 110 of the drain has a hanging wall 121 which seals on the sealing ring 109. A ring with lip 122 is adhered to the inside of the hanging wall 121. The lip 122 cooperates with the resilient finger 107 to prevent accidental removal of the mounting ring 110.

Because the ring with lip 122 is directly attached to the inside of the outlet 121, a more compact construction is obtained with respect to the embodiment 100 according to figures 1 and 2. The downside is that a separate ring with lip 122 must be produced, because otherwise the drain ring 110 is not releasing, which would require a costly shared mold.

Figure 4 shows a cross-sectional view of a combination 140 according to the invention. The combination 140 has a foam plate 141, in which a drain 100 according to figure 1 is arranged.

The mounting ring 110 is recessed in the top side of the foam plate 141, while the receiving tray 104 with the ring 103 is placed against the bottom side.

Because the finger 107 can slide relative to the lip 112, while the sealing ring 109 provides the seal, a difference in thickness of, for example, the foam plate 141 can be absorbed.

A tile layer 142 with tile adhesive 143 is furthermore arranged on the foam plate 141. The drain 115 protrudes with the outlet 114 into the second seal 113 and can also be adjusted in height, so that the top of the drain 115 is flush with the top of the tiles 142. A sealant layer 144 further provides a seal between the drain 115 and the tiles 142.
